Abstract
A touch sensitive surface has emitters and detectors arranged around a periphery of the touch sensitive surface. The emitters produce optical beams that are received by the detectors. A stylus is configured to disturb one or more of the optical beams by a variable amount when in contact with the touch sensitive surface. The variable amount depends on an amount of force applied to the stylus towards the touch sensitive surface. A controller of the touch sensitive surface is configured to determine the touch strength of a touch event performed by the stylus based on disturbances of one or more of the optical beams. The touch strength provides a measure of the amount of force applied to the stylus.
